Hi y’all, thanks for the help with my question yesterday. I did a bit of homework, and I think I’ve got things figured out. Here’s my revised plan:

  1. configure a cron job to update DuckDNS with my IP address every 5 minutes

  2. use ufw to block all incoming traffic, except to ports 80 and 443, to allow incoming traffic to reach Caddy

  3. configure the Caddyfile to direct traffic from my DuckDNS subdomain to Jellyfin’s port

Does this seem right this time? Am I missing anything, or unnecessarily adding steps? Thanks in advance, I’ll get the hang of all this someday!

      How does reverse proxy help with security? Reverse proxy is mostly there for the convenience.

        Umm… Not sure if you are serious but knowledge is meant to be shared so… A reverse proxy isn’t really for convenience, it sits between two networks and proxies traffic according to specific rules. It also has the benefit of masking the origin server a bit (like its IP) and in a lot of cases can be used as a way to ensure traffic going to a server or service that doesn’t support transport encryption actually transverses the internet within a secure tunnel.

          Yes, that’s why I said mostly. In this context reverse proxy is being used to access different ports via 80/443 from outside. That is not necessarily the use case you’re mentioning.

        Sorry, I assumed you were intelligent and sanewashed your comment.

        I assumed you were talking about the fact that internal web servers that services like Jellyfin run are often DoSable without a proxy.

        Jellyfin is quite literally a web app and perfectly safe to host on the web. Wanna prove me wrong? I’ll happily spin up an instance and throw a $500 bounty on there for you.
